shielded. Consult a doctor or the manufacturer of the device to find out if
it is sufficiently protected against external radio signals or if you have any other
questions.
Cardiac pacemakers
The manufacturers of cardiac pacemakers recommend a distance of at least 15
cm between the mobile phone and the cardiac pacemaker in order to avoid mal-
functions of the pacemaker. Persons using cardiac pacemakers should keep the
following in mind:
• They should always keep the telephone at a distance of 15 cm from their
pacemaker when the telephone is switched on.
• They should never wear the telephone in a breast pocket.
• They should use the ear on the half of the body opposite to the one with the
cardiac pacemaker to reduce the risk of malfunctions.
They should turn the telephone off immediately if there is a reason to assume
that there is a malfunction.
Explosive areas
Always turn the device off when you are in explosive areas.
Follow all of the instructions and guidelines. A risk of explosion also exists, for
example, in places where you normally have to switch off the engine of your
vehicle. In these areas sparking may lead to explosion or fire; this involves risks
of injury and danger to life. Switch the device off at petrol stations and all other
places where there are petrol pumps or vehicle garages and workshops.
Adhere to the restrictions regarding the use of radio-controlled devices in places
where fuels are stored and sold, in the area of chemical factories and places
where blasting is in progress. Areas with risk of explosion are often – but not
always – clearly marked.
The same applies below deck on ships, to the transport or storage of chemicals,
to vehicles operated by liquid fuel (such as propane or butane) as well as to
areas containing chemicals or particles in the air, such as fibres, dust or metal
powder.
